UV ABSORBING FUSED QUARTZ AND ITS USE FOR LAMP ENVELOPES |
| 摘要 |
UV ABSORBING FUSED QUARTZ AND ITS USE FOR LAMP ENVELOPES Fused quartz containing europium oxide, titanium dioxide and cerium oxide has been found to be effective for absorbing UV radiation while transmitting visible light radiation. Uses for this material include lamp envelopes and shrouds for halogen incandescent lamps and metal halide arc discharge lamps which emit both W and visible light radiation.
